Finding a fish which is below your boat is quite easy when you are using the Garmin Striker 4 Fish Finder (Part #010-01550-00) with built-in GPS. Featuring an easy-to-read 3.5" color display with handy keypad function, the Garmin Striker 4 Sonar Fishfinder and GPS Plotter assist you to hit the daily limit while others search for bites. This fishfinder includes a Garmin CHIRP (77/200 kHz) transducer that provides a higher level of clarity and detail for fish and structure than traditional transducers. The CHIRP transducer sends a continuous sweep of frequencies, ranging from low to high, then interprets them individually upon their return. Unlike other fishfinders, Garmin Striker 4 has built-in high-sensitive GPS to locate your current position accurately and quickly. More importantly, GPS allows you to mark spots where the fish are biting so you can return to them again in the future.
Garmin Striker 4 fishfinder allows you to see your positions in relation to waypoints that you have marked in the past fishing adventures. Use the waypoint map to simply check, look and sail to locations such as stumps, brush piles and docks. You can check boat's speed on the screen of your Striker 4 fishfinder so that you can make sure that you are sailing at the correct speed for the bait and for a particular fish species. The Striker 4 fishfinder package contains dual-beam transducer, transom and trolling motor mounts, tilt/swivel mount, and power cable.
